Add Picture

func (f *File) AddPicture(sheet, cell, picture, format string) error

AddPicture provides the method to add a picture to a worksheet by given picture format set (such as offset, scale, aspect ratio setting, and print settings) and file path.

For example:

package main

import (
    "fmt"
    _ "image/gif"
    _ "image/jpeg"
    _ "image/png"

    "github.com/xuri/excelize/v2"
)

func main() {
    f := excelize.NewFile()
    // Insert a picture.
    if err := f.AddPicture("Sheet1", "A2", "image.jpg", ""); err != nil {
        fmt.Println(err)
    }
    // Insert a picture scaling in the cell with location hyperlink.
    if err := f.AddPicture("Sheet1", "D2", "image.png", `{
        "x_scale": 0.5,
        "y_scale": 0.5,
        "hyperlink": "#Sheet2!D8",
        "hyperlink_type": "Location"
    }`); err != nil {
        fmt.Println(err)
    }
    // Insert a picture offset in the cell with external hyperlink, printing and positioning support.
    if err := f.AddPicture("Sheet1", "H2", "image.gif", `{
        "x_offset": 15,
        "y_offset": 10,
        "hyperlink": "https://github.com/xuri/excelize",
        "hyperlink_type": "External",
        "print_obj": true,
        "lock_aspect_ratio": false,
        "locked": false,
        "positioning": "oneCell"
    }`); err != nil {
        fmt.Println(err)
    }
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}

The optional parameter autofit specifies if make image size auto fits the cell, the default value of that is false.

The optional parameter hyperlink specifies the hyperlink of the image.

The optional parameter hyperlink_type defines two types of hyperlink External for the website or Location for moving to one of the cells in this workbook. When the hyperlink_type is Location, coordinates need to start with #.

The optional parameter positioning defines two types of the position of a picture in an Excel spreadsheet, oneCell (Move but don't size with cells) or absolute (Don't move or size with cells). If you don't set this parameter, the default positioning is move and size with cells.

The optional parameter print_obj indicates whether the image is printed when the worksheet is printed, the default value of that is true.

The optional parameter lock_aspect_ratio indicates whether lock aspect ratio for the image, the default value of that is false.

The optional parameter locked indicates whether lock the image. Locking an object has no effect unless the sheet is protected.

The optional parameter x_offset specifies the horizontal offset of the image with the cell, the default value of that is 0.

The optional parameter x_scale specifies the horizontal scale of images, the default value of that is 1.0 which presents 100%.

The optional parameter y_offset specifies the vertical offset of the image with the cell, the default value of that is 0.

The optional parameter y_scale specifies the vertical scale of images, the default value of that is 1.0 which presents 100%.

func (f *File) AddPictureFromBytes(sheet, cell, format, name, extension string, file []byte) error

AddPictureFromBytes provides the method to add a picture in a sheet by given picture format set (such as offset, scale, aspect ratio setting and print settings), alt text description, extension name and file content in []byte type.

For example:

package main

import (
    _ "image/jpeg"
    "io/ioutil"

    "github.com/xuri/excelize/v2"
)

func main() {
    f := excelize.NewFile()

    file, err := ioutil.ReadFile("image.jpg")
    if err != nil {
        fmt.Println(err)
    }
    if err := f.AddPictureFromBytes("Sheet1", "A2", "", "Excel Logo", ".jpg", file); err != nil {
        fmt.Println(err)
    }
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}

Get Picture

func (f *File) GetPicture(sheet, cell string) (string, []byte, error)

GetPicture provides a function to get picture base name and raw content embed in a spreadsheet by given worksheet and cell name. This function returns the file name in the spreadsheet and file contents as []byte data types.

For example:

f, err := excelize.OpenFile("Book1.xlsx")
if err != nil {
    fmt.Println(err)
    return
}
file, raw, err := f.GetPicture("Sheet1", "A2")
if err != nil {
    fmt.Println(err)
    return
}
if err := ioutil.WriteFile(file, raw, 0644); err != nil {
    fmt.Println(err)
}
